How to wire solar panel to 12 volts to 230 volts alternate current load and ups inverter.

In this solar panel installation it shows how to connect a solar panel to the alternate current load through ups/inverter and charge controller. You will also learn how to connect the pv panel to the battery and direct current load as well.

We have used a single unit system such as 120w, 12 volts solar panel, 100Ah, 12 volts battery and 120/230 volts automatic ups for auto on/off operation of the system. You will need all the four basic components of a solar panel installation system, example pv panel, solar charge controller pwm or mppt, battery and an inverter.

The pv panel wiring can be used for both alternate current and direct current loads. Alternate current load can be powered by ups/inverter where it uses the storage energy in the battery as backup power. It can also be used without the battery if you don't need the backup stored power later at night or shading. The way, the solar panels will direct power up the alternate current load via online ups. In addition, the direct current load can be directly connected to the charge controller only direct current load terminals.

The following solar panel diagram shows that a 120w, 12 volts solar panel is directly connected to the 12 volts charge controller. Battery and inverter are connected to the battery terminals positive and negative of the charge controller. Direct current load is also connected to the direct current output terminal of the charge controller. The 120 volts or 230 volts alternate current load such as fan and lights etc is connected to the ups output terminals.

The whole system can light up both alternate current and direct current loads at the same time. Keep in mind that, use the rated and well designed system according to your needs as you know that a single pv panel and battery will not support that much load. In addition, the charging time and rate of the battery will be too low due to other loads connected to the pv panel at once. To avoid the overload conditions you will have to connect multiple units solar panels and batteries in series, parallel or combination of series and parallel connection depends on your system requirements.

For this reason, you will have to find how much wattage solar panel do you need and what is the required amount of backup power stored by later for later use etc.

The good thing is that all the power changing process from solar power to battery and vice verse is fully automatic due to automatic ups wiring and you do not need to use an extra manual or automatic changeover or auto transfer switch to transfer the power between batteries and solar panels to the load points.
